提出了一种新的随机多址接入无线传感器网络的MAC控制协议,在发送分组的时间1+a中,采用P概率检测与1-坚持的联合控制策略,并对多通道的随机多址接入无线传感器网络进行了分析,理论分析了系统的吞吐量和多通道中不同业务的吞吐量,以及信息分组的发送时延等参数,理论分析与仿真实验结果相一致.还结合无线传感器网络的能量有效性,通过对概率P值的选取,控制忙周期侦听信道的节点数和空闲期的休眠站点数,采用休眠技术实现了系统的节能效果.通过对2种无线传感器网络控制协议的能量有效性分析,证明了改进的控制协议其节点具有更长的生命周期,更适合作为无线传感器网络的MAC控制协议.

A novel random multi-access MAC protocol for WSN using the multi-channel and the probability detection and 1-persistent access policy in the packet transmit (1+a) was proposed. The throughputs of the PDPMRM protocol and the multi-traffic were obtained. Simulations agree with the theoretical analysis. Also, the energy efficiency was analyzed for WSN by choice of probability p to control the waking nodes in busy period and the sleeping nodes in idle period. The sleeping technique realized the purpose of saving energy. By using contrast of energy efficiency between PDPMRM and improved PDPMRM, this improved PDPMRM has longer life cycle, it is more suitable for WSN.
